Upgrade your trailer lighting with this 4-Pack 6 in. Oval LED Trailer Tail Light set designed for enhanced visibility and road safety. Each light features high-output LED chips that deliver bright red and white illumination for stop, brake, turn, reverse and running light functions. Compared with traditional halogen bulbs, LED technology provides faster response time, lower energy consumption and longer service life, helping drivers behind you react quickly and safely. This multi-function surface mount design makes it an ideal solution for trailers, trucks and RVs requiring reliable rear lighting performance. Constructed with durable ABS housing and a tough PC lens, these lights are built to withstand demanding road and weather conditions. Ultrasonic welding technology ensures a sealed structure that is waterproof, dustproof and shock resistant. Designed for 12-Volt systems, each 6 in. oval light includes hard-wired connections: white wire for ground, red wire for brake/stop (high brightness), and black wire for tail/running light (low brightness). The package includes 16 self-tapping screws for secure surface mounting. Please note this unit requires hard-wire installation and is not plug-and-play. Suitable for a wide range of 12-Volt vehicles including trucks, trailers, RVs, buses, pickup trucks, semi-trailers, boat trailers and utility vehicles, this lighting kit provides dependable performance for work or travel.
